Mine is a mid 2005 DSG engine code AXX. VIN 1K6 Was having big problems with the DSG flat spotting when trying to accelerate, after slowing for say a roundabout etc, you had to come back off the gas, then go back on to pick up revs, also when slowing and turning the box would drop into 1st and rev like hell before wanting to change up. Dealer said their demo had displayed the same issues, until the 24K6 recall was performed.
Mine was done 2 weeks ago, stopped all the problems, DSG is smoother than ever, car picks up faster, and fuel econ has upped 5mpg........thought the car was good before, now even better. Also top suspension mounts changed to stop constant knocking noises, that worked, but made the steering rack noises more noticeable, so its back for a new rack!!
